﻿﻿﻿SCIENTIFIC MOTIVATIONS​How does lightning form inside a storm cloud? This is one of the greatest modern-day electrical mysteries! In the 90s researchers discovered that electric fields in storm clouds are far too weak to break down air... Yet thousands of lightning strikes hit the earth every minute. Storm clouds use some yet unknown trick to make up the difference.Our goal is to reproduce the electrical conditions inside storm clouds, where we can observe for the first time how lightning performs its unusual magic.
